GREEN BAY — The
Green Bay Packers' injury list keeps on growing.

Coach Mike
McCarthy knew about the injuries sustained by wide receivers
Randall Cobb and James Jones during Sunday's victory at Baltimore.

But he didn't
learn until Monday morning that starting outside linebacker Nick
Perry had suffered a foot injury that will sideline him at least
for this week and likely longer.

"Nick Perry
was a bit of a surprise to me. I didn't expect that,"
McCarthy said, one day after his team overcame injuries in a 19-17
victory over the Ravens.

"Obviously
James and Randall, (we) saw the injuries in the game. You just
hope for good news there."

McCarthy, as per
his custom, would not divulge any specifics of the injuries.

Perry's injury
was termed a "foot" injury, Jones' a "leg"
injury and Cobb's a "knee" injury.

He said Jones had
a chance of playing Sunday against Cleveland at Lambeau Field, but
he ruled Perry out and said Cobb would miss "multiple
weeks" while refusing to elaborate.

"I
understand your need and desire to report on it, but we also have
a football team to manage and decisions to make, and that's part
of those decisions," McCarthy said.

Elam during the first half of an NFL football game in
Baltimore, Sunday, Oct. 13, 2013. Cobb left the game with an
injury after the play.

The Packers were
already playing without four-time Pro Bowl outside linebacker Clay
Matthews, who suffered a broken thumb against Detroit on Oct. 6
that was expected to sideline him for a month.

In preseason, the
team lost starting left tackle Bryan Bulaga and running back
DuJuan Harris, the returning starter at that position, to knee
injuries.

If Cobb will miss
significant time, the Packers could place him on injured reserve
with the designation to return, which would require him to miss
the next six games.

Each team is
permitted to designate one player for return, and the Packers
opted not to use their designation on Bulaga or Harris.

Jones went down
with 9:48 left in the first quarter after getting caught up in a
pile while blocking on an Eddie Lacy run.

Cobb, who was hit
in the right knee by Ravens safety Matt Elam with 22 seconds left
in the first half after catching a 15-yard pass from Aaron
Rodgers, left the field on a cart but came back to the sideline on
crutches during the second half.

Rodgers
confronted Elam on the field after the play, accusing the rookie
safety of hitting Cobb unnecessarily low.

"I just felt
like (Elam) had enough time to make a hit in the legal hitting
zone," Rodgers said after the game.

Jones stayed on
the sideline trying to walk off the injury, then limped to the
locker room under his own power during the first half before
returning to the sideline in street clothes for the second half.

James Ihedigbo
talked to Rodgers about the difficulty defensive players have on
where to hit opponents.

"(Ihedigbo)
came over and made actually a very knowledgeable point — which I
appreciated a little intelligent banter back and forth — about
some of the issues defensive players have to deal with with the
target area," Rodgers said.

"I totally
understand that and get that. I just felt like, from my vantage
point, (Elam) had plenty of time to not take out a guy's legs in
that situation. I think he could have hit in the proper hitting
zone, and that's what I told him."

The news of
Perry's injury was surprising because he went back into the game.

Perry was injured
in the closing seconds of the first half when he sacked
Baltimore's Joe Flacco and forced a fumble. A Ravens offensive
lineman landed on Perry's right leg, but after sitting out the
third quarter, Perry went back into the game in the fourth
quarter.

"It was just
up to me and how I felt," Perry said after the game.
"You don't want to make it worse. Ultimately, it's just how I
feel. We have guys who get do the job.

"I think we
need everybody right now knowing that Clay is down. We're not
looking forward to any more injuries, that's for sure. It's just
preventative. I'll be back next week."

With Matthews
still out, Mike Neal and rookie Andy Mulumba will start at outside
linebacker against the Browns, with rookie Nate Palmer as the only
backup at the position.

If James Jones
can't play, the Packers will have to add a receiver to the 53-man
roster with only Nelson and second-year man Jarrett Boykin
healthy.

"When
injuries happen, I look at it as you have to flip the page,"
McCarthy said. "It's like anything in life, are you going to
cry about it or are you going to look at it as an opportunity to
improve? Really, these injury situations are opportunities for our
younger players or any player on our roster to jump up and take
the rope."
